Be it known that I, CARL 8. Casrnnsoiv, a citizen .ot the United States, residing at New liritain, in the county et Hartiordyand State oil Connecticut7 have invented a new and nsetul Combination Drawbolt and Lock, ot' whichthe following is a specification. i i

A The` present inventionfrelates to iinprovements in locks, and ,is more particularly directed to that type ot' lockadapted to be used on 'suit casesfand wardrobe trunks.

.a lo'cking' device in cooperative relation with a complementary meanslfor preventing openingol' the trunk or vany closure to which the device may be applied, the `complenuentary means being furtheradapted to automaticall;v draw the usual top and ybottom plates oit' the' lock ytogether as the lock lcasing is :Forcedinto place.` i n The invention y will be i best understood .troni a consideration et the Vfollowing detailed description taken iu connection with the accompanying drawing forming part of this speciiication, with the understanding. howevm that the invention `is not confined .to am7 strict conformity with the showing in the drawingabut may be changed and modified so long as `such changes and modifications inark no material departure :from the salient features 'of the invention as expressed in the appended claims. Y

ordinary wardrobe trunk their abutting or meeting edges being' indicated by the L.line F3, shown in Figs. l and 6. The top` orstrike plate si., having a def pressed or offset portion 5, spaced from the trunk cover l by 6*, andthe top plate and basevplate 6 are secured to the top of the `trunk l by means of rivets 7. A box-shaped strike or keeper 8 is struck trompa piecemof metal, (or drawn from the plate 4) with its side andrear walls lthe top plate et by means oflugs 9 projecting through slots inthe top plate Thebottoni oit the-'keeper is open. Depending from the bottoniedge oit' the top plate 4 is a tongue l() provided with a narrow flange ll projectingvr forwardly `trom said tongue7 theY ends of said iiange being rounded.

A bottom plate l2 is secured to the/lower half or body section of the trunk by rivets 13 and is providedwith an outwardlyv project-ing box-like bracket 14 sc acuredv bv ineans of lugs 11 projecting through slots in the bottoni plate l2 and 'bent overtoy the rear of said bottom plate." The bracket or strike. 8, is formed of one piece offinetal. and may be formed integral with said plate.

asing l having adlaw bar 18 at rits lower end adapted to [cooperate with the flange l1. Vhen the lock casing l'r-.is shoved inwardly towards the top plate -l so that the latch bolt lf) will Pivoted at 16 within the bracketis a lock be drawn together by reason ot' the draw bar 1S engaging and pressing dmvnwardl;T upon n as shown :in Fig. 3. The latch bolt 19 forms part of the .mechanism of the vlock 2O which secured within the lock casing 17 bv means of the inturned `lugs 2l. embracing the rear portion of said lock. The lock 20'comprises barrel 22 projecting slightlybeyond the outer edge of the lock casing 17 and isprovided with the usual slot 23 .adapted to receive a key for with- `v`drawing the latch bolt 19 from the vkeeper or strike 8. vThe interior formation of the v i n i be ofanyimproved configuration which is ordinariljfY used in standard locks. A spring 24 mounted in thev lock 2O 'engages 'a lug 25 on the latch bolt 19 to maintain the latch bolt out` wardly from the lock 20 in order that the nieans ot' the base plate at right angles to the bod57 of i embrace Y bengage'd by the strike or keeper 8, the two sections oil. the trunk will latch will always be in a position to engage the strike 3. The inner side oi the project-Y ing portion ot the latch bolt 19 isbeveled so that as hinge pin 16 and forced against the top section 1 o the trunk, therounded portion of the latch vbolt will cause the latch bolt 19 to bedepressed until it is lforced sufficiently downwardly to slip beyondV and into .the keeper 8.

ItV willbe seen that ras the'lock casing 17 is moved inwardly upon its hinge pin 16, the

draw bar 18 will' enga-ge the flange 11 and force the top plate and likewise the cover 1 of the trunk downwardly, or in other words vdraw the two sections together, so that the latch bolt 19 will engage the keeper 8 and be forced beneath and to the rear of said `keeper to lock the two sections together.

Furthermore, the roundedouter edge Y26 of the strike or keeper v8 will be engaged by the inner vedge of the top 27 of the lock casing 17, andy further assist in drawing theltwo sections ofthe trunk together inl order that .the latch bolt 19 may snap to the rear of the strike 8. v l' Figs. 6 to 9, inclusive, illustrate amodication of the device shownin Figs. 1'to 5. To the top plate 4, which is identical in construction with the top plate shown in Figs.

1 to 5, is secured the-strike or keeper 8 andV the dependino tongue V28 provided with a fia-nge 29. Upon bothsides of the tongue 28 are integrally formed shoulders 39," the ,purpose of which will be described'later.

rlhe vlock casing 31 is pivoted on a hinge pin 32 passing through perforated ears 33 ot a i Y bracket 34,7wchich is mounted onthe bottom plate 12. The shoulders fare adapted to abut. the ears. 33 of the bracket 34 whenv the two sections otthetrunk are locked together.

yA latch bolt 35,;shown in detailinFig.. 9,

' is` slidably mounted within the vlock casing.

31, and is formed of sheet `metal bent upon itself andfhavin'g a spaced'portionor'loop through which is inserted a bar 37r hav-V 36 ing the finger pieces 38 projecting" through slots formed in the sides'of theA lock casing 31. The lower end of thelatchY bolt has a case and trunk loc-ks to provide for the doustud 39, which is surrounded by a spring 40, the upper end of which engages the shoulder. 41 on the latch bolt, while the lower end of the spring rests in engagement with the lower yportion of the lock casingso that the springjwill always tend to `Jforce the latch bolt upwardly, inr order-that vit will en.

' Ikey isy inserted inv the slot 43, it will be VarmA 44 simultaneously.

the lock'casing is moved upon its by. V'slightly beyond the lock casing 31, against Vflange 29, will torce Figs. 1 to 5,'the

birrerie, which is previas@ with stitiites the other lock.- it is .further noted th adapted to rotate the barrel. and the lock The lock arm44 is rearwardly projecting portion 45 adapted to ride upon the outersur- 'lace ol the latch bolt 35 andengage indentations 46 in the latch bolt 35 in order to hold the lock arm 44 in certain predetermined positions. turned lug 47 on the lock casing 31 and prevents movement of thelatch bolt 35, when the same has been locked by a key.

The locking position ofthe lock arm- 44 is provided with a The lock arm 44 enga-ges an inshown in dotted lines in Fig. 9, and in full A lines in Figs. 8 and 9. When the lock arm is placed in inoperative position, as shown in Fig'. 9,7the latch boltmay be operated freely means ot' the finger pieces 38, projecting the tension of the spring 40. Y

The flange 29 is adapted to be engaged by adraw bar 48 of Vthe lock casing 31 when the lock casing is shoved inwardly into locking position with the strike ,or keeper 8V so` that this draw bar 48, as it engages thedraw l the two sections of the trunk together. Y l

As has been explainedwith reference to top 49 of the lock casing 31 and, likewise assist in'drawing the two sections together.

@ne of. the novel features of this invention is the provision of the depending tongue Afor the top plate having outstanding flange at the lower,` end'thereolf. These elements 2. and 28 Vand 29, respectively, in Fig. 7.

This tongue with its flange constitutes what it known in mechanics as a dowel. lin this instance', however, it nnot onlyY functions as to the lorin shown in Figs. 1 to casing 17 with its latch bolt 19 engages keeper 8while the draw bar 18' of the lock casing is engagedby the liange 11 of the tongue 10. Inthe-pother Y upper rounded portion 26 of Y the strike 8 isV adapted to be engaged by the are marked-10 and 11, respectively,in.V Fig.

ange 29 engages with the barv A4,8 of the lock casing in the second form of the invention, and is locked inits engageform of the inventionshownvin Figs. 6 `to 9, inclusive, the latch bolt 35 engages` with Y the keeper 8 and formsy one lock, -while the draw bar 48 of the lock casing 31 'is-engaged bv the flange 29 oi the tongue 28 and conor 31V in both forms ol the invention em at the lock casing 17 y braces the sides-and top, ofthe `keeper 8in addition to which the latch bolt lits 'within the keeper. ln the lorm shown in' Figs. l to 5, inclusive, a box-like bracket l-l .Gives lateral snpport to the lock casing li, in addition'to which Vthe koepel' S tltting within the lock casing adds to the lateral support. ol `the latter. In this manner, the locking of the trunk is made very rigid, and there aire no projecting parts which would be aptv to be torn oil by rough usage.
